To enable others skilled in the art to use my invention, I will proceed to describe its operation.

I introduce the steam into a reverberatory furnace through the fire-bridge. (a low wall which neath the flame of said furnace-that is, the steam is introduced between the ores containing gold or silver and the flame of a reverberatory furnace.

The steam passing over the heated ores causes certain changes and decompositions which facilitate the extraction of gold and silver by amalgamation.
